Adiabatic and non-adiabatic perturbations for loop quantum cosmology
Yu Li, Jian-Yang Zhu
We generalize the perturbations theory of loop quantum cosmology to a hydrodynamical form and define an effective curvature perturbation on an uniform density hypersurfaces .…

Convergence of Perturbations for a Big Bounce in Loop Quantum Cosmology
Yu Li, Jian-Yang Zhu
We investigate the convergence behaviors of the scalar and the vector perturbations for a big bounce phase in loop quantum cosmology. Two models are discussed: one is the universe…
